GAS-BURNER FOR STOVES.

Specification of Letters Patent.

Application fil May 22,1906- Serinl No. 318,251.

Patented April 23, 1907.

1'0 all whom it rmcty concern:

Be it known that I, JOHN BENNETT, a citizen of the United States ofAmerica, and a resident of Huntington, county of Cabell, State of WestVirginia, have invented certain new and useful Improvements in Gas-Burners for Stoves, of which the following is a full and clearspecification, reference being had to the accompanying drawings,in whichFigure 1 is a perspective view; Fig. '2 a side elevation partly insection; and Fig. 3 a

burner.

This invention has relation to that class of burners adapted for use inheating and cooking stoves, and especially to that type of burner wherethe gas and air are mixed in a o enings, these burner openings extendingt e full length of the tubular mixing chamber so as to roduce apractically continuous flame the i illl length ot the burner.

To the accomplishment of this object and such others as may hereinafterappear, the invention consists of the parts and combination of artshereinafter fully described, and particu arly pointed out in theappended claims, reference being had to the accoms ecification, in whichthe same reference 0 aracters designate like parts throughout theseveral views.

Referring to the drawings by referenceeharacters, A designates the baseplate whose ends are bent upward to form end walls a of the mixingchambers, the main mixing chamber B being attached to these upstandingend walls by means of suitable ears a lormed integral with the said endwalls.

The chamber B is substantially circular in cross-section and its endsare closed by the end walls a, and along its bottom is a series of holes6. Su ported in the end walls a, below the chain er B, is the gas supplypipe D which is provided alongits upper surface with a series of jetopenings (1, one ol these openings being arranged directly in line withone of the openings 5 in the mixing chamber, the openings 1) beinglarger than the gas open- I ingsd.

The mixingchamber B is provided with a slot running the full length ofits upper side,

and this slot is covered by a tube C which engages the end walls a andis enclosed within the chamber B except the narrow portion of its upperside which is exposed along the slot in the mixing chamber.

The tube C is provided with numerous per- 'l'orat-ions 0 throughout itsarea, the perforations which are exposed along the upper side of thetube being the burner openings, and the remainder of these perforationsopen into the mixing chamber.

It will be observed that as the gas jets up into the main mixing chamberit carries with it the proper proportioi'i of air, and the air and gasare commingled in the main i'nixing chamber B. From this main mixer thepartially mixed air and gas is jetted into the final mixer C through thenumerous line holes in that portion of the tube exposed to the interiorof the main mixer, and from this final mixing chamber the thoroughlymixed gas and air emerge from the burner openings. It will thus beobserved that I obtain practically three mixing operations, each one.more thorough than the preceding one, the first mixing being broughtabout by the arrangement of the openings (Z and b, the second mixingtaking place in the main mixer, and the 'linal mixing being caused byrequiring the mixed air and gas to pass through the numerousperforations in the tube C before issuance at the burner openings. Byreason of this thorough mixing of the air and gas I obtain a perfectblue llame the full length of the bm'ner, and this occurs even when thegas is turned on. with lull force. This complete combustion of the gasavoids the formation o'l" fumes and smoke, thereby preventingcontamination oi the air in. the room in which the burner is used. Ialso obtain the maximum of heat with a given quantity of gas. It will beobserved also that the peculiar arrangement of the burner tube has thefurther advantage o'l preventing the flame from blowing down and burningthe inside of the mixing cluunbcr.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent is In a burner of the class set forth, a mainmixing tube provided with openings in its bottom and a slot along itstop, a gas supply pipe supported thereunder and provided i In testimonywhereof I hereunto aflixlny With jet openings coincident With theopensignature in the presence of tWo Witnesses 1o ings therein, anlg afinal migier collisissing (if a this 21st day of May 1906.
